mbsinit(3C)mbsinit(3C)NAMEmbsinit() - determine conversion object status
SYNOPSISDESCRIPTION
If ps is not a null pointer, the function determines whether the object
pointed to by ps describes an initial conversion state.
APPLICATION USAGE
The mbstate_t object is used to describe the current conversion state
from a particular character sequence to a wide-character sequence (or
vice versa) under the rules of a particular setting of the category of
the current locale.
The initial conversion state corresponds, for a conversion in either
direction, to the beginning of a new character sequence in the initial
shift state. A zero valued mbstate_t object is at least one way to
describe an initial conversion state. A zero valued mbstate_t object
can be used to initiate conversion involving any character sequence.
The prototype of this function is available to applications if they
are:
a. conformant.
b. Compiled with macro with a value >=500.
c. Compiled with macro with a value >= 200112.
EXTERNAL INFLUENCES
Environment Variables
The behavior of this function is affected by the category of the cur‐
rent locale.
RETURN VALUE
The function returns non-zero if ps is a null pointer, or if the
pointed-to object describes an initial conversion state; otherwise, it
returns zero.
The behavior is undefined if an mbstate_t object is altered by any of
the functions described as "restartable", and is then used with a dif‐
ferent character sequence, or in the other conversion direction, or
with a different category setting than on earlier function calls.
ERRORS
No errors are defined.
